Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction, and more particularly to a side wall steel bar protective layer control device. Background Art
[0002] The cover thickness refers to the distance between the small cushion layer above the concrete. The concrete cover is the portion of concrete in a concrete component that protects the steel bars from direct exposure. The concrete cover is the minimum distance from the concrete surface to the outer edge of the nominal diameter of the outermost reinforcement. For post-tensioned prestressed bars, this is the distance from the outer edge of the casing or duct to the concrete surface. The minimum cover thickness is specified to ensure that concrete structural components meet durability requirements and effectively anchor the stressed reinforcement.
[0003] After searching, the utility model patent with Chinese application number CN202122744196.3 discloses a side wall steel bar protective layer thickness control device, including side wall main bars, vertical main bars, spacing positioning bars, horizontal main bars, positioning bars, steel formwork and steel bar welding clips.
[0004] When in use, the top of the steel formwork is fixed by the steel bar welding clips, and the lower part of the steel formwork lacks a corresponding fixed structure. During the concrete pouring process, the lower part of the steel formwork is prone to deviation, affecting the accuracy of controlling the thickness of the side wall steel bar protective layer. In addition, the position of the card slot for fixing the steel formwork on the steel bar welding clip is fixed, which makes it inconvenient to adjust the position of the steel formwork according to usage requirements and to properly adjust and control the thickness of the side wall steel bar protective layer, reducing its practicality.
